JTZQ-8 Fully automatic Coke Pelletizing Machine (Integrated machine for crushing, pelletizing and screening）

The reactivity and post-reaction strength of coke are important indicators guiding blast furnace production. With the trend of large-scale blast furnaces, this indicator can better reflect the thermal performance of coke and its framework role in the blast furnace, and can guide the production of coke and the use of coke in the blast furnace. The test requires that the surface of the sample be basically consistent to ensure good sample repeatability. Due to the strict requirements for the particle size and shape of the samples in the test and the need for a large number of sample portions, manual sample preparation is labor-intensive and involves many human factors, which cannot meet the test requirements.

The CXJTZQ-8 fully automatic coke crushing, pelletizing and screening integrated machine can quickly complete sample preparation and integrate sample preparation, grinding and screening. It can directly turn irregular large coke blocks into spherical coke suitable for coke reactivity and post-reaction strength tests. The equipment adopts PLC control technology and LCD display mode, combined with fully Chinese operation buttons, which can easily complete sample preparation work. It is also designed with an external dust removal port to remove coke powder during the test process. This equipment features high yield rate, convenient operation, time and labor-saving, environmental protection and safety, as well as fast sample preparation speed.

Technical indicators

1. Integrated equipment

The equipment integrates crushing, chamfering, chamfering and screening, reducing the volume of the equipment and the number of operation procedures.

2. Fully sealed design

Negative pressure vacuum system reduces dust and improves the working environment.

3. One-click operation

After adding materials, it can be started with one click, eliminating the need for manual operation and reducing the labor intensity of workers.

4. Hammer knife design

It adopts a hammer-knife design, simulating a high ball output rate by human hands and eliminating the phenomenon of blocked holes caused by coke grinding!

Working principle This equipment is composed of three sets of movable cutting knives, a cutting knife bin with round holes, a vibration device, a screening device and a control unit. It is also designed with phase failure and phase sequence protection as well as thermal overload protection. Based on the principle of impact sample cutting, the cutting knife of the equipment rotates at high speed driven by the motor, causing the coke to be continuously cut and rubbed inside the cutting knife, directly forming large pieces of coke into spherical coke with a smooth surface. The crushed coke and spherical coke fall onto the two layers of sieve plates below through the holes in the wall of the cutting knife chamber. These sieve plates are equipped with vibration devices and are always in a vibrating state. After screening, crushed coke and spherical coke will automatically fall into different sample frames.
